TRACK-SUPPORTNG DEVICE.

Application filed November 24, 1924. Serial No; `2,0G2.

To all 'iL/tom 'it may concer/a.'

Be it known that I, Vieron Sr. CLArr.

)mAo'krJrr7 a citizen of Canada, and a resident of Moncton, Ncw'lrunswick, in the .oniinion of Canada, have invented a new and improved Track-Supporting lDevice, of which the following is a description.

lily invention relates to a track supporting device and particularly to a device for Vteinporarily supporting the track under condi; tions requiring the temporary removal or a part of the 'track or the customary support for the track, for the purpose ot laying a pipe culvert, for example.

rihe general object of my invention is to provide a track supporting device of the indicated character so formed and arranged as to be readily applied to the track to bridge the temporary excavation and adapted to afford ample support for the portion of the track to which the device is applied. D

More specifically, the invention has in view the provision of a temporary. track support made up largely of track rails and which may be assembled and disassembled with facility and dispatch.

The nature of my invention and its distinguishing features and advantages will more clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a plan view of a section of a railway track having my supporting device emplaced therein;

Figure 2 is a side elevation;

Figure 3 is an enlarged transverse section in a. plane indicated by the line 3-3, Figure 1;

Figure a is an enlarged detail in side elevation.

In Figure 1 are shown railway ties 10 and track rails 11 on said ties. The numeral 12, Figure 2, indicates an excavation beneath the track rails and ties, thus leaving a portion of the track unsupported.

In accordance with my invention provide a series of compound girders, each girder made up of two or more track rails 13. One of the compound girdersis laid at each side of each track rail 11, the emplaced gir-ders at each rail thus embodying at least two track rails at each side of/each main rail.

track.

Each ojirder composed of the girder rails 13, embodies spacers or separators 14 having a longitudinal bore through which a bolt 15 .is passed, said bolts receiving nuts 115 thereby complet-ing the girder and holding` the rails 13 thereof rigidly in parallel relation.

llangers 16 are provided and advantageously these are each in the form of a short section of an inverted track rail, the hangers being disposedbetween the rails 13 of a o" girder and having the flanges 17 of the hanger rail resting on the adjacent base iianges of said girder rails 13.

The hangers 16 at the opposite sides of each track rail 11 'jointly receive beams 18 which thus extend transversely beneath the track rails 11 with their ends beneath the girders. The ends 19 of each beam 18 extend through holes 2O in the hangers 16 and the beams are held against displacement by any suitable means such as keys 21 and cot- `ters 22, for example. 1n practice the girder rails 13 are not higher than the track rails 11, thus making certain that no part of the track supporting device extends above the plane of the tops of the track rails to con stitute an obstruction to moving trains. This is especially important when the track supporting device is emplaced in a main line track. However, there may be instances in which the stated precaution may be unnecessary as for example, when the supporting device is used in sidings. rEhe use of track rails in the forming of girders is with a view to practical considerations and it will be understood that the cross section of the girder rails may be varied. It will be clear from the foregoing that the supporting device may be emplaced and removed without disturbing the relative positions of the track a rails and track ties. The use of the device also does away with the necessity of providing trestlework when an excavation is made beneath a railway track, the trestlework as is well known oerng an obstruction to the work to be done beneath the As in the illustrated example, thev under part of the supporting device, that is, the beams 18 and hangers 16, are within the planes of the ties and therefore offer no obstruction to the work to be done in the excavation Vhen the supporting device is in use as shown. it will be readily seen that the train load is transferred from the track rails 11 to the beams 18 directly therebeneath, thence to the hangers 16 and to the girder rails 13. The girder rails are nia-de of a length to bridge the unsupported length of the track and the ends ot the rails rest on the track ties remote from the excavation.4 By providing at least two rails 13 to each girder, the total number of girder rails plus the track rails provides at least l0 rails instead of two to take upthe load over the unsupported length of track.

I Would state in conclusion that While the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the saine can `be considerably varied Without departure troni the spirit of the invention as deiined in the appended claims. f y l Having thus described my invention, I claim: v

l. A track supporting device including' a pair ot girders adapted to be disposed lengthwise at opposite sides of aqtrack rail, each girder including a plurality ot rails and means tying the rails into rigid relation to constitute the girder, together With a beam adapted to be disposed transversely beneath a track rail and extending to the girders of the pair, and means supporting lsaid beam lengthwise aty opposite sides of a track rail,

each girder including a plurality of rails, and means tying` the rails into rigid relation f to constitute the girder, hangersy having flanges resting on the flanges of the girder rails, and a beam extending transversely from girder to girder at the under side thereof and having their ends supported in said hangers.

A track supporter including a pair ot girders adapted to be disposed lengthwise at opposite sides of a track rail, said girders including each a plurality of rails, spacers between the rails and transversebolts holding said rails in 'rigid relation; together vwith hangers having support on the an'ges of the girder rails, and a transverse beam at the under side of the girder rails and supported by said hangers.
